Study Notes

Kidney Structures

Cortex: The outer layer of the kidney responsible for blood filtration.
Medulla: Inner kidney tissue involved in tubular reabsorption and secretion.
Renal Sinus: Houses blood vessels, nerves, and renal calyces.
Hilum: Entry and exit point for blood vessels, nerves, and the renal pelvis.
Renal Pelvis: Funnel-shaped structure that collects urine from the major calyces.
Corticomedullary Junction: Interface between the renal cortex and medulla.

Nephron Components

A nephron consists of two main parts: the renal corpuscle and renal tubule.
Renal Corpuscle: Composed of the glomerulus (capillary network) and the glomerular capsule (Bowman's capsule).
Nephrons: Cortical nephrons (located mainly in the cortex) and juxtamedullary nephrons (with long loops in the medulla).

Urinary System Structures

Urine flow: kidneys → ureter → urinary bladder → urethra.
Ureters transport urine via peristaltic waves.
Detrusor Muscle: Collective muscular layer of the urinary bladder wall.

Renal Blood Supply

Blood supply path: Renal artery → segmental arteries → interlobar arteries.
Blood flow: Afferent arterioles → glomerulus → efferent arterioles → peritubular capillaries.

Urine Formation and Flow

Glomerular filtration occurs in the renal corpuscle, leading to capsular space and proximal tubule.
Distal convoluted tubule (DCT) connects to the collecting duct, leading to the renal pyramid.
Filtrate exits the nephron through the DCT and flows into the descending limb of the nephron loop.

Obstruction and Disorders

Obstruction in the renal pelvis prevents urine from leaving the kidney.
Issues with podocytes can damage the visceral layer of the glomerular capsule.

Miscellaneous Key Points

Major calyces merge to form the renal pelvis.
Renal corpuscle functions in the initial filtration of blood.
Highly developed microvilli in nephron segments indicate specialized functions, primarily in the proximal convoluted tubule.
Juxtaglomerular apparatus monitors sodium concentration and adjusts glomerular filtration rate.
Kidneys are positioned behind the parietal peritoneum, offering some protective structure.
